Problem

The backup job of a physical machine fails with the following error:

Backup of the "X" physical machine has failed.
Snapshot was invalidated by the source system for one or more volumes.

Background 

This error can occur for several reasons. One of the reasons is running a physical server backup job when the LVM allocation snapshot size of the LVM volumes exceeds the set size limit. The other common reason is that the snapshot was deleted.

Solution

In case the error occurred due to the deletion of the snapshot, restart the machine and rerun the backup job.

To solve the snapshot size problem, you need to increase the maximum snapshot allocation size. Do the following:

For a Linux physical machine, it can be done via NAKIVO Backup & Replication interface:

  1. Navigate to Settings.
  2. Go to the General tab and click System settings.
  3. In the Processing Options section, increase the maximum snapshot allocation size by configuring the LVM allocation snapshot size feature. 

For a Windows physical machine, do the following on the Windows machine:

  1. Open Control Panel.
  2. Go to System>System Protection.
  3. Click Configure.
  4. Adjust the Max Usage slider to the percentage you need.
  5. Click Ok.
